D 5 Notes on testing

5.1 Material

The identity test is performed using infrared spectroscopy.

5.2 Yield stress

Tensile test according to DIN EN ISO 527-2, S2 specimens according to DIN 53504; test rate v = 50 mm/min ± 10%.

5.3 Modulus of elasticity

3-point bending test: measurement in standard climate or at -40 °C in constant-temperature chamber.

Specimens: 50 mm x 10 mm x product thickness (up to max. 4 mm); support separation: 40 mm

5.4 Notched impact strength

Impact resistance test (broadside impact) according to DIN EN ISO 179-1; deviating specimen length: (50 ±1) mm; width: (6 ± 0.2) mm; thickness according to finished part thickness (up to max.

4 mm); support separation: 40 mm; test apparatus: pendulum impact tester 4J.

The specimens are given a 0.8 mm wide U-shaped notch on the broad side. The notch depth shall be 1/3 the specimen thickness. The edges adjoining the base of the notch must have a curvature radius of < 0.1 mm.

Specimens taken from molded parts with one-sided graining or paint shall be notched on the grained or painted side and placed on the support so that the center of the notch is exactly in the center of the striking plane and the notch is turned away from the direction of impact.

5.5 Impact resistance

Testing according to DIN EN ISO 179-1; deviating specimen length: (50 ± 1) mm; width: (6 ± 0.2) mm; thickness according to finished part thickness (up to max. 4 mm); support separation: 40 mm, test equipment: pendulum impact tester 4J.

Specimens taken from molded parts with one-sided graining or paint shall be placed on the support of the pendulum impact tester so that the grained or painted side faces the direction of impact.

5.6 Aging at elevated temperature

Continuous aging in mechanically circulated air at (+150 -1) °C. The test is preferably performed on complete finished parts. It is permissible to perform it on sections of finished parts. Brittling is reached when the specimen exhibits signs of disintegration typical for decomposed PP at any point (material starts to crumble).

5.7 Low-temperature behavior

Low-temperature aging of at least one finished part.

Aging temperature: (-40 ± 2) °C, aging duration: (22 +2) h.
